The operators "in" and "not in" operate on parenthesized lists of operands. They can be used with a single template parameter expanding as a list.<br><br> Person( likes in ( "apple", "banana", "chili" ) )<br>
<br>is the same as<br><br> Person( likes == "apple" || == "banana" || == "chili" )<br><br>-W<br> <br><br><br><div class="gmail_quote">On 21 June 2011 18:34, Witham, Darren <span dir="ltr"><<a href="mailto:darren.witham@citi.com">darren.witham@citi.com</a>></span> wrote:<br>

The column headers in this table made use of the forall(||) construct which happily parsed the corresponding comma separated data in the relevant spreadsheet cell to nice || separated conditions.<br>
<br>
We have since decided to use the template approach so we can store rule data in a db. We ideally want to store this data as key/value pairs in a db table where the values may contain comma separated data. The intention being these values would be processed as per the decision table.<br>
<br>
How is this achieved using a template ? I note that a column can be denoted as an array column by adding [] i.e.<br>
<br>
template header<br>
column[]<br>
<br>
<br>
However, although this appears create an ArrayColumn parser, and splits the comma separated data when running through a debugger, any attempt to access it in the template falls over in mvel code trying to call HashMap.column<br>
<br>
<br>
Any examples on how to set this up ?<br>
<br>
Thx<br>
